ELECTRICAL BONDING DEVICE.

Patented @ct. 15,1912.

To all whom 'it may concern:

. Be it known that I, HmAM C. Winnnmrs,

' a citizen of the United States of America,

residing at No. 89 Kimbell street, in the city of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Electrical Bonding Devices, of which the following is a specification.

My invention relates to electrical bonding to provide a means for electricallyibonding' adjacent electrical conducting; agents 'espe jcially adapted for use in railway service, and

so constructed and arranged that lthe bonding wires are positively held in contact with the'rails; together Withfsuch other elements and combinations as are: hereinafter set forth and claimed. 1

I accomplish these objects bymeans oft-he mechanism illustrated in the accompanying drawing, in whichi Figure l is an end elevation of a rail with my invention in place. Fig. 2 is a side elevation, with parts broken away, of a rail supplied with my invention. Fig. 3 is a side elevation of a rail showing my invention before it is securely placed in position. Fig.

4 is a side elevation of'a rail showing a.

means for placing my invention in position in. connection therewith. F1g. 5 -is a cross section of a rail showing a means for placing my invention in'position in connection therewith. Fig.6 is an end elevation of the bonding plate chuck. Fig, 7 is asectional view of the shell, M. Fig. 8 is"a detailplan view of the bifurcated jaw, U. 1

Similar letters refer to similar parts throughout the several views.

In order to make a good electrical contact between adjoining rails, it has been the custom-to connect the rails by means of electnic wires which are inserted through holes bored for that purpose in the web of the rails." It takes considerable time and expense to thus connect the wires with the rails. The wires being loose between the rails arecovered -with the dirt and lie in the moist earth, and

these wires are also injured frequently by men working on the road and people walking along the track.

I have produced a bond wire holder for and wherethey cannot be accidentally interfered with by those walking along the track.

"4 My bond wire holder comprises a plate, A, which is provided along one edge with a cutting surface, B, the putting surface, B, being rounded preferably its" shown in Figs. 2 and '3. The edge'of the plate, A, diagonally'opposite, B, is formed with a similar cutting surface, C. The plate, A, is provided with openings, D, E, extending through the plate from one surface, a, of the plate, A, toward the medial line thereof and there enlarged placed through the openings, D, E, where they are gripped and held tightly'in contact with the plate when the plate is pressed between the head and foot of the rail, as

hereinafter described, the openings being partly closed by the force exerted on the ends of the plate. The plate, A, with the wires, F, F, are then placed in contact with the rail as shown in Fig. I then rotate the plate, A, the cutting surfaces,'-B and G,

nel along the under portion of the head, G, and in the foot, H, thereof. The portions, 7), a, of the edges adjacent to the cutting surfaces, B and C, respectively, enter the said channels as the plate, A, is rotated to the po-- sition shown in Fig. 2, and the plate is held securely in connection with the rail.

' For the purpose of rotating the plate, A, I preferably use a tool, K, provided with an arm, L, adapted to pass over the head, G, and engage the side, 9, of the head opposite that occupied by the rest of the tool, K.

I provide a chuck comprising a shell, M, and a bifurcated jaw member, U, which is adapted to enter the shell, M, and which is provided at one end with a threaded portion, 10, passing through the plate, 11, at thcend of the shell, M, upon which I place the wing nut, V. Byoperating the wing to admit of the wires, F, F. The wires are thereof, during therotation, cutting a channut, V, I may thus draw the jaw member, I

U, into the shell. M, which will tend to cause the jaws, 12and 13, to be forced toward each other, engaging as they do the sides of the shell, M, which sides approach each other as shown in Figs. 5 and 7. The jaw, 12. has a gripping lug, m, and the aw, 1,3,

has a gripping lug, m, which engage oppo- I it end of the shell, M, is squared at T, and the handle bar, S, is placed thereon by means of whlch the shell and the aw, U, are rotated,

forcing the plate, A, in the position between the head and foot of the rail and thereby closing the openings, D, E, tightly upon the wires, F, F. i

'I do not limit myself to the use of the tool herein shown and described for the purpose of placing the plate, A, in position, becauseit can be done with a wrench or other similar instrument, althougl'i the tool described 15 a very complete and practical one for the purpose.

What I claim as my invention and desire to secure by Letters Patent is:

l. A bond wire holder comprising a plate provided with openings therein for holding bonding wires; each end of said plate provided witha cutting edge throughout a p0rof the head of the rail and in the top side of the foot. into which the ends of the plate will be "forced.

2. A bond wire holder comprising a plate provided with openings, extending from one edge toward. "the" medial linethereof, for

wires therein; said plate placed, when in opera ion, with its ends projecting into the head and foot of a rail; wires extending into said openings in the plate.

3. An electrical bond, comprising two retaining plates provided with openings therethrongh; wires placed in said openings re spectively; adjacent rails; one of said plates between thehead and the foot of each rail; a means on said plates for causing a channel to be cut in the head and foot of the rails whenrsaid plates. are rotated, into which channel the ends of the plates will project.

In testimony whereof I have atlixed my signature in presence of two witnesses.
